Problems solved by technology

When the blood flows through the heat exchange module and then flows through the oxygenation module, heat loss will occur; on the contrary, when the blood passes through the heat exchange module after gas exchange, the gas exchange efficiency will be lost

Abstract

The present invention provides an extracorporeal membrane lung oxygenator, comprising: a main casing, a first end and a second end cover arranged at both ends of the main casing, the main casing includes: a central cavity for blood to flow in, and A temperature control cavity and a gas exchange cavity spirally surrounding the central cavity; an annular space is formed between the temperature control cavity, the gas exchange cavity and the inner wall of the main casing; the first end cover is provided with a blood inflow channel that communicates with the central cavity , and the temperature control medium outflow channel and the oxygenation medium outflow channel spirally surrounding the blood inflow channel; the second end cap is provided with a blood outflow channel communicating with the annular space, and a temperature control medium spirally surrounding the blood inflow channel The inflow channel and the oxygenated medium flow into the flow channel; the flow cross-sectional area of ​​the temperature control medium flowing into the flow channel gradually decreases; the flow cross-sectional area of ​​the oxygenated medium flowing into the flow channel gradually decreases. The invention can make the pressure of the oxygen-enriched gas and the temperature control medium evenly distributed, and realize the best heat and gas exchange efficiency.

Description

technical field [0001] The invention relates to an extracorporeal membrane oxygen supply device for assisting cardiopulmonary function, in particular to an extracorporeal membrane oxygenator. Background technique [0002] Extracorporeal membrane oxygenation (ECMO) is an extracorporeal circulatory system with both heart and lung assist functions. Through the arteriovenous cannula, the blood is drained from the body to the outside. After membrane oxygenation, the oxygenated blood is perfused into the body by the pump to maintain the blood and oxygen supply of various organs of the body. It is performed on patients with severe cardiopulmonary failure. Breathing heart support for a longer period of time allows the patient's heart and lungs to rest adequately and wins precious time for further treatment and recovery of heart and lung functions. [0003] The oxygenation function module and the heat exchange function module of the existing membrane lung oxygenator are mostly indep...
